To all whom it may concern.-

Be it known that I, ARTHUR BURDIOK, a citizen ofthe United States, residing at Brighton, in the county of Lagrange, State of Indiana, have invented certain new and useful Improvements in Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to doors, and more particularly to barn-doors.

One object of the invention is to provide an exceedingly simple, inexpensive, durable, and efficient door for the purposes stated.

Another object is to provide a sectional or double door and arrange the sections with relation to each other whereby one section may be moved independently of the other or whereby all the sections may be moved simultaneous] A still further object of the invention resides in the provision of a sectional door whereby when all the sections are moved to open the barn the opening is clear of obstacles, permitting the entrance or exit without hindrance.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims.

any suitable material.

In the drawings, Figure 1 is a front elevation illustrating a portion of a barn, shed, car, or other housing, the sections of the door being shown in closed position. Fig. 2 is a view similar to Fig. 1, showing the upper section of the door open. Fig. 3 is an edge view of both sections of the door. Fig. 4 is a vertical section taken transversely through the mutually-engaging portions of the'two doors.

Referring now more specifically to the accompanying drawings, the reference character 1 designates the side of a barn, car, or the like, the reference characters 2 and 3, respectively, designating the upper and lower doorsections.

Arranged along the upper portion of the barn, car, or the like 1 and in alinement with the upper edge of the upper door-secton is secured in any suitable manner a track 4 of This track is designed to support and guide the rollers 5 of the hangers 6, which latter have their lower ends secured, by means of rivets, bolts, or the like,

to the said upper door section, as clearly shown in the drawings. It will be seen that the rollers 5 have their peripheries grooved, forming flanges upon the edges of the periphcry to prevent the rollers accidentally leaving the track.

The lower end of the upper door-section is interlocked with the upper end of the lower door-section 3. For instance, the lower end of the upper door-section is provided with a channel shaped metallic or other form of guide 6, having a slot 7 in its under face. This guide, which forms a guide for the travel of the lower door-section, is rectangular in cross-section; but it is obvious that the same may be of any other form. At any rate, the said guide, as it may be called, as shown, is arranged horizontally with relation to its length projecting upon opposite sides of the door-section and is secured in any suitable manner to the lower end of the said door-section, the same having a double set of rollers 8 secured in alinement therein, one set with relation to the other, the rollers being spaced from the upper and lower walls of said housing or guide to permit their easy rotation and especially to permit the track 9, secured by rivets, screws, or the like to the upper end of the lower door-section, to ride thereupon.

It will be seen that the track 9 projects upon opposite sides of the lower door-section, and it will be understood that the same is at least twice as long as the width of the door, and since it is carried by the lower door-section itis obvious that when the latter is moved to the right or left the track 9 travels with it. By reason of thetrack 9 projecting upon the sides of the door-section the lower section is suspended from the upper section, the track of the former working upon the tops of the rollers confined within the guide of the upper door-sections, as clearly shown in the drawings. ging of the track 9, a brace 10 is employed and has one of its ends secured to the outer end of the track 9 in any suitable manner and its opposite end secured in any suitable manner to the corresponding edge of the lower door-section, as shown at 11.

In order to lock the door-sections together, the inner ends of the channel-shaped housing 6 and the track 9 extend a short distance beyond the corresponding edges of the respective door-sections, each having a perforation for the reception of the pin or other element 12, which, in order to prevent displacement,

In order to prevent possible sagmay be secured to the free end of the chain or other suitable element 12'', connected to the upper door-section in any suitable manner.

It will thus be understood from the foregoing that when the doors are locked together both the upper and lower sections may be moved for opening the barn or the like, the upper door-section depending entirely for its support'upon the upper or main track and the lower door-section suspended therefrom or from the rollers carried thereby. Of course the upper and lower sections may be moved independently of each other by withdrawing the pin 12 from the aforesaid perforations of the corresponding sections.

I claim 1. The combination with a barn having a door-opening, of a track secured along the side of the barn near the upper edge of said opening, an upper door-section having rollers associated therewith and mounted upon the said track, whereby the said section may be moved along the track, a guide secured to the lower edge of the upper door-section, a lower doorsection having a track secured thereto and extended laterally beyond one side edge there' of, the second-mentioned track working within the said guide, whereby the upper and lower sections are interlocked and whereby one section may be moved independently of the other.

2. The combination with a barn having an opening therein, of a track secured to the barn near the top of said opening, an upper doorsection slidably mounted upon said track, a guide secured to the lower edge of said upper door-section and having series of rollers mounted therein and in alinement one series with relation to the other, said guide also having a slot in its lower face, a lower door-section having a track secured upon its upper edge, the second-mentioned track extending beyond the sides of the lower door-section and titted within the said guide for sliding movement upon the tops of the rollers within the latter, the lower door section fitting within the slot of said guide, and the secondmentioned track extending beyond one side edge of the lower door-section and movable with the latter, and means for locking the sections together, whereby both sections may be moved simultaneously.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR BURDIGK.
